How can I set up password-less SSH login?
I am using ssh to connect to a remote server. I am prompted to provide a password each time, but I recall being able to set up a sort of authentication key, so that passwords were not required.
However, it has been ages, and I have forgotten just about everything about it, except the word "key". One of those things you set up and forget, and I never quite understood it to begin with.
How is it done?
